What Is a Janitorial Service? How Is It Different from Cleaning?

If you’ve searched for cleaning help for your business, you’ve probably seen both terms, “janitorial services” and “commercial cleaning”, used as if they mean the same thing. Sometimes they do. But often they don’t, and hiring the wrong type of service because you assumed they were identical is a frustrating and avoidable mistake.

Here’s the actual difference, where the overlap is, and how to figure out which one your business needs.

What Is a Janitorial Service?

Janitorial service is ongoing, routine maintenance cleaning. Think of it as the regular upkeep that keeps a building functional and presentable day to day, the work that gets done nightly or weekly so you arrive in the morning to a clean space.

A janitorial contract typically covers:

• Trash and recycling removal
• Restroom cleaning, disinfection, and restocking
• Vacuuming carpeted areas
• Sweeping and mopping hard floors
• Wiping down high-touch surfaces (doorknobs, light switches, counters)
• Break room and kitchen cleanup
• Glass and mirror cleaning
• Dusting desks, furniture, and fixtures

These are recurring tasks done on a set schedule, nightly, three times a week, or whatever frequency the business needs. The goal is maintenance: keeping the space at a consistent standard over time.

Janitorial service doesn’t usually require specialized equipment beyond a mop, vacuum, and cleaning cart. It’s hands-on, consistent, and relationship-based, the same crew learns your building, knows where everything is, and builds a routine around your space.

What Is Commercial Cleaning?

Commercial cleaning is a broader category. Janitorial service falls within it, but so does a lot more, specialty services, deep cleaning, and one-time or periodic work that goes beyond what a regular janitorial crew handles.

Commercial cleaning includes things like:

• Carpet extraction and deep cleaning
• Hard floor stripping, waxing, and buffing
• Kitchen hood system and deep degreasing
• Post-construction cleanup
• Window washing (interior and exterior)
• Pressure washing
• Upholstery cleaning
• Biohazard or trauma cleanup
• Move-in / move-out cleaning

These are services that require specialized equipment, training, or chemicals. They’re not done on a nightly basis, they’re scheduled periodically, often quarterly or annually, or as needed for specific situations.

A commercial cleaning company might do all of these. A janitorial service company might specialize in only the recurring maintenance side. Some companies do both, and that combination can be genuinely useful if you want one contractor handling everything.

Where They Overlap

In practice, many cleaning companies use “janitorial” and “commercial cleaning” interchangeably in their marketing. When you call for a quote, they may offer both the routine maintenance service and the specialty add-ons under the same contract.

The overlap is real because most businesses need both. You need someone to handle the nightly routine (janitorial), and you also need periodic deep cleaning and specialty services (commercial cleaning) a few times a year. The best contracts bundle this together with a recurring base rate and scheduled add-on services throughout the year.

Which One Does Your Business Actually Need?

Here’s a practical guide based on business type:

You need janitorial service if:

• You have a commercial space that’s used regularly and needs consistent upkeep
• You want a crew coming in on a regular schedule (nightly, 3x/week, weekly)
• Your primary need is trash removal, restroom cleaning, floor maintenance, and surface sanitation
• You want a long-term relationship with a contractor who knows your building

This covers most offices, professional services businesses, medical practices, small retail spaces, and similar facilities.

You need commercial cleaning services if:

• You need a specific project completed: post-construction cleanup, move-out cleaning, a one-time deep clean
• You need specialty services: carpet extraction, floor stripping and waxing, window washing, hood cleaning
• You’re looking to supplement an existing janitorial contract with periodic deep cleaning

You probably need both if:

You’re a restaurant, healthcare facility, or any business where routine maintenance alone isn’t enough. Restaurants need nightly front-of-house cleaning plus monthly or quarterly kitchen deep cleans. Medical facilities need daily maintenance plus periodic deep disinfection of equipment areas. Warehouses need weekly floor sweeping plus quarterly scrubbing.

Most commercial cleaning companies that offer janitorial service can also schedule periodic deep cleaning as part of the same contract. It’s worth asking upfront whether that’s included or whether you’d need to book it separately.

What Excellence Janitorial Services Offers

For most of our clients, the relationship starts with a recurring janitorial contract, then adds specialty services, carpet cleaning, floor waxing, kitchen deep cleans, on a scheduled basis throughout the year. It keeps the building consistently clean without the administrative overhead of managing multiple vendors.

Frequently Asked Questions

Is janitorial service the same as commercial cleaning?

Not exactly. Janitorial service is a type of commercial cleaning, specifically the recurring, routine maintenance work done on a regular schedule. Commercial cleaning is the broader category that also includes specialty and one-time services like carpet cleaning, floor stripping, post-construction cleanup, and more.

What’s included in a standard janitorial contract?

A standard janitorial contract typically covers trash removal, restroom sanitation and restocking, vacuuming, floor mopping, surface wiping, and break room cleanup, performed on your specified schedule. The exact scope varies by contractor and is usually spelled out in the service agreement.

Do commercial cleaning companies also do janitorial work?

Many do. Plenty of commercial cleaning companies offer both recurring janitorial contracts and specialty project work. If you want one contractor handling all of it, regular maintenance plus periodic deep cleaning, look for companies that explicitly offer both and can structure a contract that includes scheduled specialty services throughout the year.

What’s the difference between janitorial and housekeeping?

Housekeeping typically refers to cleaning in hospitality settings, hotels, resorts, healthcare facilities. It often includes making beds, replenishing amenities, and room turnover. Janitorial service refers to commercial building maintenance: offices, warehouses, restaurants, retail. There’s some overlap, but they serve different industries and have different scope expectations.

How do I know if I need janitorial service or a one-time deep clean?

If your space needs regular upkeep on an ongoing basis, that’s a janitorial contract. If you have a specific situation, you just completed construction, you’re moving into a new space, or you want to reset your building after years of deferred cleaning, that’s a one-time commercial cleaning job. Many clients start with a deep clean, then transition to a regular janitorial contract once the baseline is established.

Can I get both janitorial and deep cleaning from the same company?

Yes, and that’s often the most practical setup. Having one contractor who handles both your routine maintenance and your periodic deep cleaning means they already know your space, your access requirements, and your standards. It eliminates the coordination overhead of managing two separate vendors.
